Professional Applications & Engineering Value

This M20 set screw delivers critical engineering solutions for industrial applications requiring maximum holding power and vibration resistance. The alloy steel construction with Rockwell C45 hardness provides superior strength that prevents deformation under extreme mechanical stress, while the extended tip design creates deeper engagement with mating components for secure positioning of shafts, collars, and gears. The headless hex drive configuration allows for flush installation in space-constrained assemblies, making it ideal for machinery, automotive, and manufacturing equipment where precision set screws must maintain alignment without protruding. The metric coarse threads (M20x2.5mm) with Class 6g tolerance ensure reliable performance in high-vibration environments, solving common issues of component slippage and misalignment in heavy-duty industrial applications.

Specification Summary & Compliance

This set screw features precise metric thread specifications with M20x2.5mm coarse spacing and Class 6g thread fit according to ISO standards. The extended tip maintains tight dimensional control with tip diameter of 15mm (-0.43mm to 0 tolerance) and tip length of 10.36mm (-0.36mm to 0 tolerance). Manufacturing complies with DIN 915/ISO 4028 specifications for dimensional accuracy and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors.
